MANUFACTURE OF METALLIC-SURFAClED- INDIA-RUBBER FABRIC.

SPECIFICATION forming part of Letters Patent No. 278,206, dated May22,1883.

Application filed August 11, 18 82. (Spccimens.) V

To all whom it may concern Be it known that I, NELsoN S. WHITE, ofCanton, in the county of Norfolk and State of Massachusetts, a citizenof theUnited States, have invented a new and useful Improvement in theManufacture of Metallic Surfaced India-Rubber or Gutta-Percha Fabric, ofwhich the following is afull, clear, and exact description.

- My invention relates to the manufacture of bronze-finished fabrics;and it consists in coatin g a close-textured fabric with a compositionof plastic india-rubber, gutta-percha, or other like material adapted tobecome set or fixed by evaporation or heat, and upon and into thesurface of which while yet plastic the bronze Dowder or laminae isspread and incorporated bypressure.

I prefer to use in "practicing my invention either of thecompositionsdescribed in Letters Patent Nos. 202,427, 238,372, and238,496, granted Charles A. Evans, in about the proportioutherein named,with the exception that the coloring matter or material may be omittedtherefrom, although, of course, I do not wish it to be understood thatit may not be used, if desired. The compositions described in saidLetters Patent consist, substantially,

of india-rubber or gutta-pereha, or both, dissolved in naphtha, and asuitable filling material used for giving bodyto the mixture, cheapeningand coloring it; but, in lieu ot'a 3 plastic compound of this naturecontaining an evaporizing agent, the evaporation of which fixes or setsthe rubber or gutta-percha, Imay use a plastic compound adapted to beset or fixed by heat. Any suitable fabric may be used, and I mentionparticularly cloth, leather, and paper as among the more desirable.

The composition is applied in one or more coats to the fabric, and whileplastic or before .it sets or becomes fixed the bronze powder or laminaespread upon the surface of the last coating in a uniform layer, and isrolled or otherwise compressed therein, and the fixing or setting of thecomposition by evaporation or by heat permanently fastens the powder orlaminae to the fabric.

It will be obvious, of course, that the plastic composition will take orpermit of a large amount of the powder being used, and that the powderor laminae, when worked into its surface, is very securely fastened orheld, so that a very permanent and brilliant bronze finish is obtained.

It will be seen, also, that a holding medium of the character describednot only serves to fasten large quantities ofthe powder or laminre tothe fabric in a substantial manner, but, owing to its elasticity orflexibility, it permits the fabric to be folded, stretched, ormanipulated Without damaging or in any way disturbing the bronze finish.

I prefer to use, for obtaining brilliancy of finish, bronzing materialin the shape of laminze rather than powder, and to apply it dry,although it may be applied in a liquid form.

The fabric m aybe pebbled during the course of its manufacture or afterthe powder has been applied, if desired.

It will be seen that the plastic rubber or gntta-percha compoundprepared to be set or fixed by heat or evaporation acts as a mordant infixing and setting the bronze powder or laminae, which is incorporatedtherewith.

Having thus fully described my invention, I claim and desire to secureby Letters Patent of the United States- 1. A close-textured fabriccoated with a plastic composition containing rubber,guttapercha-,orboth, adapted to beset by evaporation or heat, upon andin which coating bronze powder or laminre is spread and embedded, allsubstantially as and for the purposes described.

2. As a means of bronzing fabrics, a plastic composition or solutioncontaining india-rubher or guttz percha, or both, adapted to becomefixed or set by heat or evaporation, spread upon thefabric, and in whichthe bronze powder or lamina: is incorporated by pressure, allsubstantially as and for the purposes described.

3. The combination of a close-textured fab-' ric, a coating ofindia-rubber and gutta-percha, or either compound, and a surfacing ofbronze powder or laminae incorporated by pressure into the coating whilethe same is plastic, all substantially as and for the purposesdescribed.

4. The process of bronzing fabrics, consistwhile plastic and unitedthereto by pressure, ing in coating the fabric with one or more allsubstantially as and for the purposes delayers of plastic gntta-perchaor india-rubscribed.
